Before a meteorological dataset can be defined, at least one meteorological station must be added to the watershed using the Station Tool  from the Watershed Setup module. Additionally, meteorological stations added to the watershed can only be edited within the Watershed Setup module. For instructions on creating, defining, editing, moving, removing, or deleting water quality stations, refer to Define a Water Quality Station. Once the desired meteorological stations have been specified from the Water Quality module, the required meteorological parameters must be defined. Meteorological datasets are created and configured using the Meteorological Dataset Editor.
